Application filed May 13, 1899. Serial No. 7161695. (No model.)

To all whom t may concern: d', as shown in Fig. 4. Each roller C O' isBe it known that I, WILLIAM AGAR, a citiactuated by a coil-spring e,Fig. 6, fixed at zen of the United States, residing at Chicago, one endto the interior of the roller and at (Pullman,) in the county of Cookand State the other end to a liXed shaft e', on which the oflllinois,haveinvented anew and usefulImroller rotates and which in turn issupported 55 provementin Window-Adj ustments, ofwhich by brackets e2.

The same result is atraised or lowered freely to any desiredpositained by locating the rollers above the height l5 tion withoutpossibility of binding, and yet to which the sash normally rises andthen 65 so arranged that th'e sash will remain where having the sashabove its normal position placed even under a constant jarring action.when the Vtapes are wound onto the rollers.

The adjustment is of peculiar value when Figs.2 and 6 show the twostrips of 'tape as used in connection with a car-window andis formedfrom a single slotted piece, being 2Q illustrated in the accompanyingdrawings as united at e4. 7o applied to such a window. rlhepulley-Stiles are connected by a slotted In the drawings, Figure l is abroken intecross-piece E, supplied with a sash-stop f for rior View ofthe side wall of a car supplied limiting the upward movement.

The sash issuspended by metallic provided with slots h to permit horizontal stripsof tape d, flanking the grooves a and movement of the roller. passingabout hollow spring-actuated rollers The spring-held guide-roller andattendant C C', located some distance above the sash, parts, afterassembling, are inserted, barrel 95 and the sash balanced and guided andthe foremost, into a socket in the vertical sash tension at the rollersC C counteracted by edge. The roller is preferably grooved, andspring-held guide-rollers D, located near the its groove formspractically a continuation of four corners of the sash. The tape stripsd the sash-groove a. The bottom of the roller- 5o are convenientlysecured to the sash by screws groove projects somewhat beyond the grooveroo in the sash, however, and bears firmly against the metallic verticalguide c or c", as'the case may be. 'Thesash edge itself does not contactwith the pulley-stile, as shown by the space at z', Fig. 5. Thus itappears, since the rollers are held under sufficient tension to preventthe sash contacting at any point on its vertical edges with thepulley-Stiles, that wedging of the sash is impossible. The tension ofthe guideroller spring, in fact, is suficient to overcome the force ofthe liftingrollers and cause the sash to remain in any desired position.

To lock the sash in its closed position and further aid in preventingthe sash from sete tling down under a jolting action, such as ispeculiar to railway-trains, a peculiarly-arranged spring-held lockingdevice is provided.

This comprises a bell-crank Gr, pivotally secured in a casing G',setinto the bottom part of the sash and provided with a nearly-hori-Zonal arm 7c and a depending arm k', a rod joined at its inner end tothe depending arm of the bell-crank and provided at its outer end withan angular part engaging' a notch on the guide-piece c', and a spring7195 serving normally to hold the rod k2 in its lock-ing position. Uponinserting the fingers at thepart G' for the purpose of raising the sashthey lirst engage the arm 7c of the bell-crank and unlock the sash,after which it is raised with extremely slight effort. At the desiredvposition the hand-pressure on the bell-crank is released and the freeend of the rod k2 bears against the track d, contributing a frictionalforce tending to prevent settlingof the sash. If desired, of course, anotch maj7 be provided at an elevated position for the end of the rod toenter, though this is ordinarily an unnecessary precaution.

The device is usefully applicable to vertically-sliding sashes in manysituations'. Any desired number of guide-rollers may be provided, thoughthere should be at least two at each vertical edge of the sash toprevent wedging.

Fig. 7 shows a barrel of elliptical eross-section, which may replace theone of circular cross-section where it is desired to use a narrow sash.

What I claim as new, and desire to secure by Let-ters. Patent, is` l l;The combination with two pulley-Stiles provided with projecting verticalguide-bars having smooth inner edges, a sash provided at its verticaledges with grooves receiving said guide-bars, and spring-held groovedrollers carried by said sash, the grooves whereof project slightlybeyond the bottoms of said sash-grooves and bear throughout theirtraverses upon the smooth adjacent edges of said guide-bars,substantially as and for the purpose set forth.

' 2. The combination with two pulley-'Stiles provided with projectingvertical guide-bars, a sash provided att its vertical edges with grgovesreceiving said guide-bars, draft-excluding lining of felt, or the likeat said sashgrooves, contacting with said guide-bars, and rollerscarried by said sash and projecting into said sash-grooves and bearingupon said guide-bars, substantially as and for the purpose set forth.

' 3. The combination with two pulley-Stiles, each provided with acentral projecting guidebar and with stops parallel to and flanking saidguide-bar, of a sash confined between said stops andv provided at itsvertical edges with barrel-receiving sockets and grooves receiving saidguide-bars, said vertical sash edges being outof contact with thepulleystiles, barrels D2 in said sockets provided with slots havingouterends affording stops, rollercarrying blocks D in said barrels,springs confined between the blocks and the inner ends of the barrelsand tending to force said blocks outward, rollers for said blocks havinggrooves projecting normally beyond the bottoms of the sash-grooves andbearing upon said' guide-bars,`and pins affording axes for the rollersand having their ends projecting beyond said blocks into said slots,whereby the outward movement of the blocks is limited when the sash isremoved, substantially-as and for the purpose set forth.
